I understand most non-enterprise WD drives ship with TLER (Time Limited Error Recovery) disabled. That means that the drive will aggressively try to fix bad sectors -- even if that means going "non responsive" for several minutes. That's OK for the desktop, but for RAID operation it's better to use TLER so that the RAID controller can flag the problem immediately.
There is a DOS utility from WD to enable TLER. But that involves pulling the drives out of the DNS-321, plugging into a PC, rebooting DOS, etc. Has anyone come up with a Linux script that can do it from within the DNS-321 itself? E.g. ssh into the DNS as root, run the script to enable TLER.
